Blowdown testing offers a cost-effective experimental tool to replicate the aerothermal conditions in numerous high speed systems. The wind tunnel must replicate the inlet operating conditions, while the spatial and time dependent inlet flow conditions should be assessed carefully. This paper provides a design methodology and rules that ensure adequate flow conditioning in high inlet pressure wind tunnels suitable for subsonic and supersonic operation with mass-flow limits ranging from 1 kg/s to 25 kg/s, Reynolds numbers from 103 (1/m) to 4x107 (1/m), and Mach numbers from 0.01 up to 6. The quality of the proposed flow conditioning system was evaluated using stereo PIV measurements combined with hotwire, Pitot probe, and total flow temperature traverses.

用于三音速高压空气热测试的流量调节系统

排污测试提供了一种经济高效的实验工具,可以在众多高速系统中复制空气热条件。风洞必须复制进气口的运行条件,而与空间和时间有关的进气流条件应仔细评估。本文提供了一种设计方法论和规则,可确保在适合于亚音速和超音速运行的高入口压力风洞中进行适当的流量调节,质量流量限制范围为1 kg / s至25 kg / s,雷诺数为10 3(1 / m)到4x10 7(1 / m),马赫数从0.01到6。建议的流量调节系统的质量是使用立体声PIV测量结合热线,皮托管和总流动温度来评估的。
